Police properly subpoenaed a cell phone companys data that showed a suspects movements, the 9th District ruled recently. Patrick Griffin appealed his murder conviction, asserting among other arguments that the trial court should have suppressed location information obtained from his cell phone provider. The court overruled his assignments of error and upheld his conviction.
Griffin was tried and convicted for killing a neighbor, Alberto Cookie Gutierrez. Investigators had identified Griffin as a person of interest when they traced the last number dialed on Gutierrezs phone to him. During the investigation they subpoenaed records from his cell phone company.
Testimony at trial showed that embedded in the record of each cell phone call was information that shows the general location of the cell phone when the call is made. A cell phone transmits a radio signal that is intercepted by the service providers nearest antenna. Each antenna has three sides. When a customer makes a call, the log records which antenna received the call and on which side.
If the cell phone moves during a call, it will shift to a different side of the antenna or to a different antenna. The call log also includes the antenna and side of the antenna in connection with the phone when the call ends.
